Abstract

Ein Stellantrieb für ein Rotorblatt einer Windkraftanlage ist mit einem elektrischen Motor und einem Frequenzumrichter versehen, der einen aus einem Stromnetz zu speisenden Gleichrichter, einen an den Gleichrichter angeschlossenen Zwischenkreis, und einen Wechselrichter zum Speisen des Motors aufweist, wobei der Zwischenkreis in einem netzgespeisten Normalbetrieb des Frequenzumrichters eine vorgegebene Nennbetriebsspannung führt. Des Weiteren ist eine an den Zwischenkreis angeschlossene Hilfsenergieversorgungseinrichtung vorgesehen. Die Hilfsenergieversorgungseinrichtung umfasst einen Energiespeicher, der eine Stützspannung zur Verfügung stellt, die weniger als 80% der Nennbetriebsspannung des Zwischenkreises beträgt. Eine Diode ist zwischen den Energiespeicher und den Zwischenkreis geschaltet und hinsichtlich ihrer Durchlassrichtung so angeordnet, dass sie einen Stützstrom aus dem Energiespeicher in den Zwischenkreis speist, falls die Zwischenkreisspannung unter die Stützspannung fällt. Die Diode verhindert einen Stromfluss zwischen dem Energiespeicher und dem Zwischenkreis, wenn die Zwischenkreisspannung größer als die Stützspannung ist. Eine Ladevorrichtung für den Energiespeicher weist eine geringere Ladespannung als die Nennbetriebsspannung des Zwischenkreises auf.
